Polymarket Traders Pocket Massive Profits on Iran Ceasefire, Stoking Insider-Trading Fears

Significant gains by Polymarket traders betting on a US-Iran ceasefire have ignited widespread speculation regarding potential insider trading. Blockchain analysts have identified multiple accounts that made highly precise and lucrative wagers, with one user achieving a 3,500% return on their investment. These incidents have renewed calls for stricter oversight of prediction platforms, prompting US lawmakers to propose bills aimed at preventing government officials from wagering on sensitive geopolitical events. In response, Polymarket has updated its integrity rules to explicitly prohibit trading based on confidential or illegal information.
